FIREARM-MAGAZINE FASTENER.

Specification of Letters Patent.

Patented Mar. 8, 1910.

Application filed. October 21, 1908. Serial No. 458,744.

To all whom it may concern:

Be it known that I, JOHN D. PEDERSEN, of Jackson, in the county of Uintaand State of WVyoming, have invented certain new and useful Improvementsin Firearm-Magazine Fasteners; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to thecharacters of reference marked thereon, which form part of thisspecification.

The object of my present invention is to provide an improved means forholding the inner spring tubein position in a tubular magazine forfirearms.

Figure 1 shows on an enlarged scale the outer end of a-tubular magazinefor firearms with my improvements applied and in position. Fig. 2 is alongitudinal sectional view on the same scale. Fig. 3 is a detailed viewshowing the end of the outer magazine tube. Fig. l is a detailed viewshowing the outer end of the inner magazine or spring tube. Fig. 5 is adetail of a spring actuated detent employed in the construction. Fig. 6is a detailed view showing the plug and head removed from the tubeparts.

Referring to the reference letters and figures in a more particulardescription, 10 indicates the head by which the inner magazine tube ismanipulated and which is preferably knurled on its outer side as shown.This head is provided with a plug part 1O adapted to fit closely in andreceive the outer end of the inner magazine tube or spring barrel 11.The plug part 10 is provided with a socket to receive the pin 12 and thespring 13 actuating the same, and is also provided with an aperture toreceive the pin 14, which secures the plug in the outer end of thespring tube 11 and which also provides as to one end a projectionadapted to be received in the L-shaped slot 15 in the outer end of theouter magazine tube 16. The inner tube 11, as well as having the opening11 which receives the pin 14, also has an opening 11' which receives theprojecting point 12' of the pin 12. The arrangement of these parts issuch that when in position the opening 11 will allow the point of thedetent to project suflicient-ly to become operative and the inner tubestill serve to retain the detent in its position in the socket.

It is evident that when the position of the projecting portion of thepin let registers with the longitudinal portion of the L- shaped slot,that the inner tube can be in serted or withdrawn, and that when theinner tube is rotated with reference to the outer tube to bring the pin14 into the transverse portion of the L-shaped slotthe inner tube willbe locked against longitudinal movement therein. When the parts arebrought into this relative position the point of the detent will beprojected into the longitudinal portion of the slot and hold the innertube with the head 10 against rotation, except when sufficient force isapplied to retire the detent on account of the inclined wedge-shapedform of its projecting end. It may also be noted that when the pin 14 ispassing down the longitudinal portion of the slot the angular form ofthe projecting end of the detent causes it to retire while being crowdedin to the end of the outer tu e.

The construction herein shown and described is efficient in maintainingthe inner tube against accidental displacement and is simple andinexpensive to build.

What I claim as new and desire to secure by Letters Patent is:

1. The combination of the outer tube having an L-shaped slot in its end,the inner tube and head having a fixed projection to engage in thetransverse portion of the slot and a spring detent arranged to engage inthe longitudinal part of the slot, substantially as set forth.

2. The combination of the plug having a socket, the spring presseddetent in the socket, the pin carried by said plug the inner tubefitting the plug and having openings for the detent point and the pinrespectively, and the outer tube having an L-shaped slot at the end inwhich the pin and detent are engaged, substantially as set forth.

3. The combination of the outer tube hav- In Witnesse whereof, I haveaflixed my siging an L-shaped slot in its end, the inner nature, inpresence of two Witnesses, this tube and head having a fixed projectionto 10th day of October 1908. engage in the transverse portion of theslot, JOHN D. PEDERSEN. and a spring detent arranged to engage withVitnesses: the outer tube and secure it against acci- EMMA S. HEssE,dental rotation, substantially as set forth. SARAH E. CLARK.
